Abstract: An inkjet head for ejecting ink droplets is disclosed which includes: a nozzle unit having metal thin plates and a piezoelectric device, adapted to eject the ink droplets; a printed circuit board supplying to the piezoelectric device a drive signal for causing the nozzle unit to eject the ink droplets; a support supporting the nozzle unit and the printed circuit board in opposing relationship to each other; an earth contact disposed on the nozzle unit; a ground contact disposed on the printed circuit board, held at a reference potential; an electrically conductive elastic member disposed between the earth and ground contacts, such that portions of the elastic member are in electrical contact with the earth and ground contacts, respectively; and a movement limiter limiting movement of the elastic member to thereby prevent the elastic member from being disengaged from the earth and ground contacts.

Abstract: An ink jet printer including a stationary frame; a tank supporter which is provided in the stationary frame and which supports at least one ink storing tank storing at least one sort of ink; a recording head which records an image on a recording medium by ejecting a droplet of the ink, and which has at least one ink flow inlet; at least one ink delivering tank which delivers the ink and has at least one ink flow outlet; at least one ink supply tube which is provided between the tank supporter and the ink delivering tank and through which the ink is supplied from the ink storing tank to the recording head via the ink delivering tank, wherein the delivering tank provides at least a portion of at least one ink delivering channel connecting between the ink supply tube and the recording head; a head holder which includes a main portion holding the recording head and the ink delivering tank, and which is movable relative to the stationary frame so that the recording head records the image on the recording medium; a

Abstract: An inkjet printer including: (a) a recording head operable to eject an ink onto a recording medium so as to perform a recording operation on the recording medium; (b) an ink source unit provided to store the ink that is to be supplied to the recording head; and (c) an ink delivery unit provided to delivery the ink supplied from the ink source unit, to the recording head. The ink delivery unit has a delivery chamber which has a delivery chamber inlet and a delivery chamber outlet, such that the ink can be delivered through the delivery chamber inlet from the ink source unit, and such that the ink can be delivered through the delivery chamber outlet toward the recording head. The delivery chamber is defined by a wall held in substantially parallel with a horizontal plane, and is elongated in a direction parallel with the wall. The delivery chamber inlet and outlet of the delivery chamber are positioned in respective positions which are substantially diagonal relative to each other.
